Abstract

A back mirror comprising a plurality of kinds of mirrors different in longitudinal-transverse magnification, wherein a mirror having a necessary longitudinal-transverse magnification can be instantly set; and a room mirror. Three kinds of mirrors different in longitudinal-transverse magnification are each stuck to the respective lateral surfaces of a regular triangular prism, and the center shaft of the regular triangular prism is intermittently rotated by a motor, stopping at 120-degree intervals; thus, the arrangement is such that, of the three kinds of mirrors different in longitudinal-transverse magnification, one having a necessary longitudinal-transverse magnification can be set. In addition, the regular triangular prism has the shape of a prism of uniform regular triangle. Further, it is to be understood that the longitudinal-transverse magnifications of the three kinds of mirrors different in longitudinal-transverse magnification be 1 to 1, 1 to 2, and 1 to 5. However, the setting of longitudinal-transverse magnifications is optional. Thereby, one piece of information about the range of rearward visual field and about ascertainment of rearward far-near distance can be increased to three pieces of information. Further, instantaneous switching between the range of rearward visual field and the rearward far-near distance is effected, thereby efficiently increasing the amount of information about the range of rearward visual field and about the rearward far-near distance which are required during traveling, and promoting safety in traveling.

Description

Description Rearview mirrors and room mirrors that enhance the safety of rear view confirmation

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pack mirror and a room mirror suitable for increasing the amount of information in a rear view range and a rear perspective distance while a vehicle is traveling, and for enhancing safety during traveling. Background art

Conventionally, the back mirror and the room mirror of a vehicle have been checked for their rear view with a single mirror with a constant vertical and horizontal magnification. Therefore, in order to change the direction of the rear view range, the mirror itself was moved, the back was checked while driving, and safety measures were taken.

The conventional rearview mirror and a single room mirror with a fixed vertical and horizontal magnification have the disadvantage that only a limited rear view range can be confirmed because the rear view range and the rear perspective distance are constant. .

Also, changing the range of view required moving the mirror itself. Moving the mirror and setting it is difficult to do instantaneously, which has the disadvantage of hindering driving.

The drawbacks of the conventional back and room mirrors are simply the fact that a fixed mirror provides a fixed rear view and a fixed rear perspective distance. In order to change the rear view range, it is necessary to move the mirror itself and set it to an appropriate position. .

Therefore, in the present invention, by providing a plurality of types of mirrors having different vertical and horizontal magnifications, it is possible to obtain confirmation information of a plurality of rear view ranges and a plurality of rear perspective distances. The aim is to increase the amount of information required to check the rear of the vehicle while traveling, and to provide a back mirror and a room mirror that enhance safety while traveling.

Further, according to the present invention, it is possible to instantaneously switch from a plurality of mirrors having different aspect ratios to a mirror having a required aspect ratio depending on a running condition. As a result, the rear view range and the rear perspective distance are The system switches instantaneously, so that you can get the information for confirming backwards as needed while driving. Obtaining information on a plurality of rear visibility ranges and a plurality of rear perspective distances instantaneously in this way effectively increases the amount of information for further confirmation of the rear, and improves rearview mirrors and room mirrors to improve driving safety. The purpose is to provide one. Disclosure of the invention

In the present invention, three types of mirrors having different vertical and horizontal magnifications are provided, and three types of mirrors having different vertical and horizontal magnifications are provided on each side surface of a regular triangular prism. As a result, three types of mirrors having different vertical and yellow magnifications are provided, as in the present invention, instead of a single conventional mirror having a constant vertical and horizontal magnification, and information for confirming the rear view range and the rear perspective distance is provided. However, there is a back mirror and a room mirror that spread from one piece of information to three pieces of information.

In the present invention, a mirror having a required aspect ratio can be set by rotating a central axis of a regular triangular prism equipped with three types of mirrors having different aspect ratios by a motor. This makes it possible to instantaneously switch between the rear view range and the rear perspective distance. In addition, the effect of increasing the amount of information for checking the rear of the vehicle while driving and improving the safety of the vehicle while driving is exhibited.
